“…The sketch of the apparatus and methodology of collecting of the data was presented in our previous papers [15,18]. Briefly, the applied set up allowed measurement and identification of the reaction products by detecting their emission and it consisted of a water cooled cation source, magnetic mass selector, collision cell, and an optical spectrometer equipped with sensitive multichannel photon-counting detector [15][16][17][18]. The source was of a colutron-type and it produced protons from H 2 gas being under pressure of 100 Pa.…”

Abstract.Investigations of the ion-molecule reactions provide insight into many fields ranging from the stellar wind interaction with interstellar media, up to medicine and industrial applications. Besides the applications, the understanding of these processes is itself a problem of fundamental importance. Thus, interactions of protons with the gas-phase furan molecules have been investigated for the first time in the energy range of 50-1000 eV exploiting collision-induced emission spectroscopy. Recorded spectra reveal emission of the atomic H β to H θ lines of the hydrogen Balmer series and the molecular bands of vibrationally and rotationally excited diatomic CH fragments created in the A 2 Δ and B 2 Σ − electronic states. The measurements of the emission yields of the excited fragments by recording their intensities at different projectile energies have been performed. The highest yields have been observed for production of hydrogen atoms which intensities rapidly decreased with increasing principal quantum number n. From the H (n = 4-7) intensity ratios depopulation factors of hydrogen excited states have been determined at each impact energy and possible collisional mechanisms leading to enhanced production of the hydrogen atoms have been suggested. We compare and discuss our results with improved data set of proton collisions with tetrahydrofuran (THF) molecules, the hydrogenated derivatives of furan.

Fast N( 2 D) atoms colliding with CH 4 at 10-200 eV CM yield CH(A,B), NH(A) and H(n P 4) emission. From 10 to 50 eV CM the CH yield decreases, exceeding greatly that for N( 4 S) and N þ ( 3 P) + CH 4 collisions. This indicates N( 2 D) insertion. Above 50 eV CM the CH yield increases again, approaching the values found with N( 4 S) and N þ ( 3 P). Here the CH formation is chemically unspecific (ÔshatteringÕ). The NH(A) yield decreases monotonically for all three projectiles. N( 2 D) insertion is here unimportant, in contrast to NH(X) from N( 2 D) + CH 4 . At E CM >50 eV CM , all projectiles give NH(A) according to the Ôbilliard ballÕ model.
