Note: this table provides some material definition with standard properties. Advanced user will want to define their own table of materials, which can be done with the routine GSMATE, described below.

CALL GSMATE (IMATE,CHNAMA,A,Z,DENS,RADL,ABSL,UBUF,NWBUF) Stores the constants for the material IMATE in the data structure JMATE.

IMATE

( INTEGER) material number;

CHNAMA

( CHARACTER*20) material name;

A

( REAL) atomic weight;

Z

( REAL) atomic number;

DENS

( REAL) density in g $cm-3$ ;

RADL

( REAL) radiation length in cm;

ABSL

( REAL) absorption length in cm. This parameter is ignored by GEANT, but it has been kept in the calling sequence for backward compatibility;

UBUF

( REAL) array of NWBUF additional user parameters;

NWBUF

( INTEGER) number of user words in UBUF.

IMATE

(INTEGER) material number. If IMATE=0 then all materials will be printed. If IMATE<0 the material number -IMATE will be printed without the header describing the value of the various fields.
