Energy Range 920 – 1380 MeV at CMD - 2
The cross section of the process e+e− → ωπ0 → π0π0γ has been measured in the c.m. energy range 920–1380 MeV with the CMD-2 detector. Its energy dependence is well described by the interference of the ρ(770) and ρ(1450) mesons decaying to ωπ. Upper limits for the cross sections of the direct processes e+e− → π0π0γ, ηπ0γ have been set.

The cross section of the process e+e− → ηγ has been measured in the 600-1380 MeV c.m. energy range with the CMD-2 detector. The following branching ratios have been determined: B(ρ → ηγ) = (3.28 ± 0.37 ± 0.23) · 10 , B(ω → ηγ) = (5.10 ± 0.72 ± 0.34) · 10 , B(φ → ηγ) = (1.287 ± 0.013 ± 0.063) · 10 . Evidence for the ρ(1450) → ηγ decay has been obtained for the first time. Budker Institute of Nuc...

ROTATIONAL ASSIGNMENT OF NEW BANDS IN THE NO , EXCITATION SPECTRUM IN THE SPECTRAL RANGE OF 15600 cm TO 15633 cm
Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...
