Orsay, December 17, 1993 Dear Colleague, Thank you for your message and for your interest in the evaluated atomic masses of nuclei. Please find below the procedures on how to access and copy the files of "The 1993 Atomic Mass Evaluation" from NNDC (USA and Canada), NEA-DB(Western Europe and Japan) or IAEA (other countries). I hope everything will work out well. If it does'nt, please contact me or contact the person in charge in one of the Nuclear Data Centers. Of course if you need any special information, please ask, it will be my pleasure to try to provide it to you. Best regards, Georges Audi ********* A - GENERAL INFORMATION ********* ********* A - GENERAL INFORMATION ********* (December 6, 1993) I - INTRODUCTION The table of masses (part I) and the table of nuclear reaction and separation energies (part II) of: "THE 1993 ATOMIC MASS EVALUATION" by G.Audi and A.H.Wapstra Nuclear Physics A565 (1993) 1 and 66. (December 6, 1993) are available electronically at the Nuclear Data Centers. A total of six files can be obtained. The first file, mass_exp.mas93, contains the table of masses as printed in part I. The next two files correspond to the table of reaction and separation energies in two parts of 6 entries each, as in part II: rct1_exp.mas93 for S2n, S2p, Q(a), Q(2B), Q(ep), Q(B-n) rct2_exp.mas93 for Sn, Sp, Q(4B), Q(d,a), Q(p,a), Q(n,a) The last three files with names mass_rmd.mas93, rct1_rmd.mas93 and rct2_rmd.mas93 are identical to the first three files except that the values resulting from the few experimental data, listed in table B of part I of our publication, are replaced by values that we recommend based upon estimates from systematic trends. Values in these files are exact (unrounded) copy of the published ones. * They can conveniently be used for calculations. * None of them should be copied in a publication as given in these files, but instead, the rounded values published in the above Journal should be used.

These six files, along with a documentation file "READMASS.ME", are located in the subdirectory SA0:[SCR.MASSES]. These may then be copied on to the user's computer using the FTP "GET" command, or the DECNET "COPY" command. The user name of the anonymous account is BNLNDC. * TCP/IP: use the `FTP' command, to connect to BNLND2: ex: ftp bnlnd2.dne.bnl.gov (or 130.199.112.132) User (identify yourself to the host): bnlndc Command: cd masses Command: get mass_exp.mas93 Command: quit * DECNET: use the DEC `DIRECTORY' and `COPY' commands, for bnlnd2 (or 44436 or 43.404). ex:$dir bnlnd2"bnlndc"::sa0:[scr.masses] $copy bnlnd2"bnlndc"::sa0:[scr.masses]mass_exp.mas93 * II - ATOMIC MASSES FROM NNDC ON-LINE SYSTEM: 1 - Access to the On-Line service: One can access the NNDC (National Nuclear Data Center, Brookhaven National Laboratory, USA) On-Line service through a network or a remote modem. The service is available on an NNDC VAX Alpha computer. Presently, there is no charge for the On-Line service. Via modem: The NNDC VAX Alpha computer can be accessed via modem using the telephone number 516-282-5390. After getting the connect signal, type a carriage return, wait and then type a second carriage return. The VAX login prompt should then appear on your terminal. Via networks: * TCP/IP (internet): use the `TELNET' command to access the computer node BNLND2. Its address is BNLND2.DNE.BNL.GOV (or 130.199.112.132) * DECNET: use the `SET HOST' command with address BNLND2 (or 44436 or 43.404) The VAX login prompt will appear and you should proceed as follows: * Username: NNDC * Enter NNDC assigned authorization code (or GUEST):GUEST (or your authorization code if you have one) The authorization code "GUEST" allows a new user limited amount of CPU time to become acquainted with the system. 2 - Retrievals or Copying of files: Once you are logged into NNDC online service you can retrieve from various different numerical or bibliographic data bases, or simply copy files containing computer codes, documentation, or mass tables. In order to copy files containing mass tables you will proceed as the following: After successful login select the option FILES. Within this option select the data item MASSES and indicate which of the six files and documentation you will like to copy over to your computer. After the selection of file(s) you will automatically be in SEND option and you will be asked which network you will want to use to transfer your file(s). After that the system will query you about your destination address, your password (it does not echo), and the file name that you are transferring. The system will respond if the transfer was successful. You can then choose to do further retrievals or logout. 3 - Logout: When terminating a retrieval session, enter or select LOGOUT. 4 - Authorization: For authorization for access to NNDC online service, user can supply the necessary information while logged in with 'GUEST' authorization as indicated above or write to NNDC at the following address: Address: On-Line access National Nuclear Data Center Brookhaven National Laboratory Building 197D P.O.
