ScientificConstants[GetIsotopes] - list the descriptors of selected isotopes

Calling Sequence

GetIsotopes( 'element'=elem, prop_name, output_opt )

Parameters

'element'=elem

-

(optional); restrict to isotopes of the given element

prop_name

-

(optional); restrict to isotopes with property(ies) prop_name defined. This parameter can be repeated to specify multiple properties.

'output_opt'

-

(optional); equation of the form output=form, where form is one of 'symbols' (default) or 'atomicnumbers', specify form of isotope descriptors to be returned

Description

• 

The GetIsotopes() command returns an expression sequence containing selected isotopes of elements of the periodic table in the ScientificConstants package.

• 

If the 'element'=elem option is given, only isotopes of the given element elem are returned, where elem can be any valid descriptor of an element.

• 

If any prop_name option(s) are given, only elements with these properties defined are returned.  The prop_name option(s) must be isotopic properties.

• 

If the 'output=symbols' option is given, the isotopes are returned in the form [atomic_number, mass_number].  This is the default.

• 

If the 'output=atomicnumbers' option is given, the isotopes are returned in the form [atomic_number, mass_number].

• 

The sequence of isotopes is ordered first by atomic number, then by mass number.
