Phosphorus - 15P: isotope data

Naturally occurring isotopes

This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of phosphorus are listed (including any which occur naturally) below.
Isotope Mass / Da Natural abundance (atom %) Nuclear spin (I) Magnetic moment (μ/μN)
31P 30.9737620 (6) 100 1/2 1.13160
Isotope abundances of phosphorus
Isotope abundances of phosphorus. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes.

Radiosotope data

Further data for naturally occuring isotopes of phosphorus are listed above. This table gives information about some radiosotopes of phosphorus, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.
Isotope Mass / Da Half-life Mode of decay Nuclear spin Nuclear magnetic moment
29P 28.981801 4.14 s EC to 29Si 1/2 1.2349
30P 29.978314 2.50 m EC to 30Si 1
32P 31.973615 14.28 d β- to 32S 1 -0.2524
33P 32.971725 25.3 d β- to 33S 1/2
