Explanation of the KEYWORDS

The KEYWORDS are designed to tell a reader what experimental results are reported in an article and what the authors have concluded from those results. The conventions used here are generally the same as those used since 1964 in the journal Nuclear Physics, A few minor changes have been forced by the limitations of the computer printout. A list is given below of several symbols that may cause confusion. This list supplements the table on the inside back cover. The KEYWORDS are given as a 'string' of words and symbols. Each string begins with a 'data category', NUCLEAR MOMENTS, RADIOACTIVITY, or NUCLEAR REACTIONS. There follows a 'measured' sentence which gives the nucleus (for MOMENTS, RADIOACTIVITY), or reaction (for NUCLEAR REACTIONS) and the physical quantities actually measured. Properties of the nucleus (for MOMENTS), t h e d e c a y (for RADIOACTIVITY) or the reaction (for REACTIONS) which can be deduced from the experiment are added to this first sentence after a semicolon (;). Additional 'deduced' sentences list other nuclei for which level properties can be deduced and give a description of those properties. A final sentence is s o m e t i m e s added to give particular details about the experiment.

A coded REFERENCE has been added at the end of each KEYWORD string. Journal names are indicated b y t h e ASTM 'CODEN' a b b r e v i a t i o n s . The abbreviations can be identified by referring to page vi or by occasional checking of the reference list, where all refererence are given in detail.
