The one-color, 2+1 resonance-enhanced multiphoton ionization (REMPI) s
pectrum of boron atoms (2p 2P(j)degrees) is studied between 304 and 35
0 nm. The most intense peak is at 346.10 nm for 4p 2P(J)degrees <-- <-
- 2p 2P3/2-degrees. The recorded spectrum includes a new np Rydberg se
ries. We report laser wavelengths and new atomic energy levels and sug
gest 2+1 REMPI as a convenient method for the detection of atomic boro
n.
